A couple of California-based developers created Breathometer in 2013. It’s a smartphone app used to measure an individual’s blood alcohol content (BAC) within seconds. Given the immediate results, the app and popular car service Uber have partnered to get too-drunk individuals home safely.

TechCrunch reported individuals at half the legal limit in California, which is .04 BAC or higher, will be prompted to either “Get Home Safe” or “Stay Nearby.” If users choose to get home safely, they’ll have the option to order a cab, Uber, or a designated driver, rather than attempt getting behind the wheel. And if they stay nearby, they’ll have additional options, such as “Find Some Food,” “Grab A Room,” and “Activity.” The activity option is exactly how it sounds: it occupies users until they’re no longer tipsy or drunk.

“Access to a dependable and on-demand ride solution directly from our app for anyone that has been consuming alcohol is critical,” said Breathometer CEO Charles Michael Yim. This partnership comes after the app’s drunker users frequently requested an option to call a driver to take them home.

According to their website, the original Breathometer offers a simple headphone jack connection, is easily shared, and doesn’t require a mouthpiece. But Breathometer Breeze detects and monitors alcohol consumption with a simple Bluetooth wireless connectivity, wearable design, and “next generation sensor.” Soon there may be Breathometer Mint, a version of the app that will detect and monitor breath quality and hydration.
